Here is an excerpt:

• “For to me, to live is Christ and to die is gain” (Philippians 1:21).
• “When Christ, who is our life, is revealed, then you also will be revealed with Him in
  glory” (Colossians 3:4).
  These statements form a foundation for understanding grace as a product of our new birth in
  Christ. He lives in us to enable us to do what He has commanded us to do. Previously I was
  under the law and condemned by it, but now I’m no longer under the law. I’m under grace.
  Christ lives in me. He enables me to do what He has commanded me to do. A believer has to grasp this concept if he is to ever become mature in the Lord. He has to come to the end of himself and start realizing what he can’t do before he can grasp what God can do in and through him. This book isn’t just another step-by-step process that promises instant maturity, but an encouragement for believers to see their relationship with the Lord in a new way.
  The Christ life is not merely trying some new plan for spiritual growth; it is learning to live out
  of His power. It is learning to appropriate the power of God and put it to use for His glory.” p.14
